Provenances and fertilizer on early growth cedar seedlings
Navroski, Marcio Carlos; Tonett, Erasmo Luis; Mazzo, Marcos Vinicius; Frigotto, Taciana; Pereira, Mariane de Oliveira; Galvani, Luan VieiraThe aim of the study was to evaluate the initial development of different provenances and the influence of base fertilizer and coverage on growth of Cedrela fissilis seedlings. Provenances of seeds were collected in Lapa, PR, Fernandes Pinheiro, PR and Itaara, RS. After germination, the seedlings were transplanted to plastic bags of 500 cm³, filled with commercial substrate. Total height (h), stem diameter (sd)...
Shoot multiplication of two Sequoia sempervirens genotypes with addition of sma...
Meneguzzi, Aline; Konzen, Enéas Ricardo; Navroski, Marcio Carlos; Camargo, Samila Silva; Pereira, Mariane de Oliveira; Rufato, LéoSequoia sempervirens (D. Don) Endl. is a conifer which produces high-quality wood with potential industrial applications. However, the species shows low germination rates. This study was devoted to optimizing a protocol for shoot multiplication of S. sempervirens through micropropagation. Two genotypes, adapted to southern Brazil, constituted the source of explants for consecutive experiments aiming in vitro mu...
Cold-tolerance and silvicultural features of Australian red cedar in southern B...
Navroski, Marcio Carlos; Pereira, Mariane de Oliveira; Borsoi, Geedre Adriano; Kalil Filho, Antonio Nascim; Nascimento, Bruno; da Rosa, Diego PereiraAustralian red cedar is a widespread species in Southeast, Midwest and Northeast regions of Brazil, which achieves high productivity. It has wood of excellent quality for noble purposes. However, in Southern Brazil it presents growth adjustment problems due to frost occurrence. The aim of the study was to verify cold tolerance and silvicultural potential of Australian red cedar in two locations in Southern Braz...
MULTIPLICAÇÃO DE Handroanthus chrysotrichus (MART. ex A. DC.) MATTOS
Pereira, Mariane de Oliveira; Navroski, Marcio Carlos; Reiniger, Lia Rejane SilveiraO presente trabalho teve como objetivo avaliar a multiplicação in vitro de ipê-amarelo em diferentes concentrações de 6-benzilaminopurina (BAP). Segmentos nodais de plântulas obtidas da germinação in vitro de sementes foram utilizados como fonte de explantes, sendo inoculados em meio nutritivo ½ WPM contendo diferentes concentrações de BAP (0, 2, 4, 8 e 16 µM). O experimento foi conduzido em delineamento inteir...
Hidrogel como condicionador de substrato para produção de mudas de Eucalyptus d...
Navroski, Marcio CarlosCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; The use of polymers hidroretentores mixed to the substrate, has the function of water retention and release in a gradual way to the plant, and may increase the efficiency of irrigation, reducing the consumption of water and fertilizers. The objective of this research was to evaluate the feasibility of using the hydrogel substrate added to the sowing o...
INFLUÊNCIA DO POLÍMERO HIDRORETENTOR NA SOBREVIVÊNCIA DE MUDAS DE Eucalyptus du...
Navroski, Marcio Carlos; Araujo, Maristela Machado; Cunha, Fernando da Silva; Pasquetti Berghetti, Alvaro Luis; Pereira, Mariane de oliveiraO objetivo do estudo foi avaliar o efeito do uso do polímero hidroretentor em mudas de Eucalyptus dunnii cultivadas em vasos, relacionando com frequências de irrigações. Foram utilizadas mudas de aproximadamente 25 cm de altura, as quais foram plantadas em vasos preenchidos com 3,5 L de solo. O experimento foi realizado em delineamento inteiramente casualizado, com 15 repetições de uma planta em esquema bifator...
